[ale] How to expand to full-path name?

[Jeff Lightner]

"whence" is my preference but since bash doesn't have it and ksh also
understands "which" that is "what" I use in both shells.  

(I'm tempted to ask "why" I have to but "where" would I go from there?)

One tool that would be of great help in this problem is 'whence' as in:

rhws/home/esoteric> whence ksh
/bin/ksh

Gives you the full path to the program or script as long as it's in your

path.  All you have to do is strip off the program name.

Problem is, that is strictly ksh, it does not work in borne.
